The methods of measurement of the oscillating field threshold amplitude, ΔB ϱ , are reviewed. As this quantity increases, an effective resistance occurs. The dependence of ΔB ϱ upon current and frequency for monofilament and multifilament conduct

A model describing ac superconducting composite behaviour by taking account of the boiling transition of liquid helium, used as a refrigerant, is described. A comparison of the resultant volt-ampere characteristics with the experimental values proves

The emergence of some apparent resistance is discussed for different cases of inductive as well as of non-inductive coils wound with non-ideal type II superconductors and placed into an external magnetic field oscillating with some low frequency. For
